Abstract Title: Microstructural and Mechanical Properties Control using Direct Laser Deposition in IN718 Ni-superalloy

Authors: Abdullah Alhuzaim, Luke Carter, R. Mark Ward, Moataz Attallah

Abstract: Investigations were performed for IN718 Ni-superalloy built using DLD to assess the role of DLD parameters on controlling the microstructural development, notably the grain size/morphology, precipitates types/distribution, and texture. To achieve this, thin walled structures were built by varying DLD process parameters; laser power, powder feed rate, scanning speed, and laser mode (continuous versus pulsed), and characterised to rationalise the influence of DLD parameters, also employing statistical design of experiments to assess the sensitivity of the parameters. A heat flow model was used to elucidate the microstructural and hardness development. The results showed a significant potential for microstructural control via DLD, while generating builds with porosity <0.01%.

The laser power and mode can be used to control the degree of mechanical and microstructural anisotropy in the builds, as well as the amount of micro-segregation and Nb-rich intermetallics, due to the variation in the heat distribution within the meltpool.
